Procedure for making LPCM DVD
by Andrew Randrianasulu 31 Jan '24

31 Jan '24

Start cinelerra-gg from terminal so you can see terminal output Open your source in cinelerra-gg as usual, choice format settings, go to DVD creation window. Select all values as you need, click ok, wait for batchrender window to appear In it, select second line and change codec to RAW PCM, and set it to 16 bit, signed, byteorder Lo-Hi (big endian) click "start". Cingg will finish but job is not! from terminal, note location of dvd.sh file and open it in editor running /dev/shm//dvd_20240116-182336/dvd.sh INFO: [mplex] mplex version 2.1.0 (2.2.7 $Date: 2012/11/17 01:55:16 $) **ERROR: [mplex] Unable to open file /dev/shm/dvd_20240116-182336/dvd.ac3 for reading. so mcedit /dev/shm//dvd_20240116-182336/dvd.sh and set mplex parameter " -L 48000:2:16" so full string will look like mplex -f 8 -L 48000:2:16 -o $dir/dvd.mpg $dir/dvd.m2v $dir/dvd.lpcm note, lpcm extension is important! now mv pcm file into same but with new extension (in theory you can change audio file extension into lpcm at batchrender window, not tested) mv /dev/shm//dvd_20240116-182336/dvd.pcm /dev/shm//dvd_20240116-182336/dvd.lpcm run script: bash-5.1$ /dev/shm//dvd_20240116-182336/dvd.sh running /dev/shm//dvd_20240116-182336/dvd.sh INFO: [mplex] mplex version 2.1.0 (2.2.7 $Date: 2012/11/17 01:55:16 $) INFO: [mplex] File /dev/shm/dvd_20240116-182336/dvd.m2v looks like an MPEG Video stream.

I'm thinking about making "use PCM" checkbox in (already a bit crowded) DVD creation window ..lets see now it will progress ... example files attached ...

HDV 1080i to DVD 16x9 with MP2 audio
by Terje J. Hanssen 29 Jan '24

29 Jan '24

As I could not recall it : Loaded a HDV 1440x108i with native MP2 stereo audio, and then Create DVD 16x9 rendering does transcode the audio to AC3 by default. Video is displayed with correct aspect ratio using VLC and . Input #0, mpeg, from 'dvd.mpg': Duration: 00:06:58.08, start: 0.160000, bitrate: 8269 kb/s Stream #0:0[0x1bf]: Data: dvd_nav_packet Stream #0:1[0x1e0]: Video: mpeg2video (Main), yuv420p(tv, bt470bg, top first), 720x576 [SAR 64:45 DAR 16:9], 25 fps, 25 tbr, 90k tbn Side data: cpb: bitrate max/min/avg: 8000000/0/0 buffer size: 1835008 vbv_delay: N/A Stream #0:2[0x80]: Audio: ac3, 48000 Hz, stereo, fltp, 224 kb/s Is it possible to get MP2 audio; if possible how and where to set it on the create DVD or Batch render window? I tried to check FFmpeg there, but could not see MP2.

HDV is really 4 channel?
by Andrew Randrianasulu 29 Jan '24

29 Jan '24

https://trac.ffmpeg.org/ticket/1258 see attached to this ticket modded decoder ... I wonder if Terje's audio really 4ch? if so,may be we can decode it to 4* wav first, then encode them correctly to bluray lpcm / dvd pcm / ac3 ...

OT? test dvd for multichannel audio
by Andrew Randrianasulu 27 Jan '24

27 Jan '24

http://www.dolby.free.fr/Dvd.htm someone posted this link to wikipedia's article on MPEG multichannel (old mp2 variety). it all in French, but ISO with spinning diskette picture hopefully understanable. Around 60 mb. http://www.dolby.free.fr/Soft/Fichier%20Image%20du%20Dvd%20Test.zip

Attempt at making byteorder setting/info consistent (Big endian on the right)
by Andrew Randrianasulu 27 Jan '24

27 Jan '24

right now if you encode PCm it will be Big Endiansetting on the right, but it will become left-choice if you try to load same file back into cin

From DV to MPG to DVD Video + PCM Audio
by Terje J. Hanssen 26 Jan '24

26 Jan '24

I want to showcase this procedure using alternative tools, and in case this sooner or later can be of some use for Creating DVD with CinGG.. *1. From DV Video w/native LPCM to DVD-compliant MPG using FFMpeg (version 4.4.4 on Leap 15.5) 2. From MPG w/o re-encoding to DVD structure and iso using DeVeDeNG (version 4.17.0 from packman) 3. Burn DVD iso with K3b from DeVeDe (or optional using Xorriso etc) * So far step 3 is not tested yet. Playback of the final mpg movie is tested with VLC and FFplay - not real tested with DVD disc in standalone players. *1.
